Add Azure (EntraID) OIDC Example

[RyanGelinas]

Add example for Azure OIDC login, as documented by @xfact-joseph-p in semaphoreui/semaphore#1434, which worked for me

It is incomplete, it should also require scopes.

That's the exact config I used in my working setup. I suspect there is a default scope that is enough for Semaphore. The examples for Authelia, Gitlab, Keycloak and Okta don't include a scopes definition either.

I had to define this configuration for getting everything working properly:

        "azuread": {
            "icon": "microsoft",
            "display_name": "Sign in with EntraID",
            "client_id": "REDACTED",
            "client_secret": "REDACTED",
            "redirect_url": "http://localhost:3000/api/auth/oidc/azuread/redirect",
            "endpoint": {
                "issuer": "https://login.microsoftonline.com/*tenantid*/v2.0",
                "auth": "https://login.microsoftonline.com/*tenantid*/oauth2/v2.0/authorize",
                "token": "https://login.microsoftonline.com/*tenantid*/oauth2/v2.0/token",
                "userinfo": "https://graph.microsoft.com/oidc/userinfo",
                "jwks": "https://login.microsoftonline.com/*tenantid*/discovery/v2.0/keys"
            },
            "scopes": [
                "openid",
                "email",
                "profile",
                "User.Read"
            ]
        }
